Question

Standard entropy of X2, Y2 and XY2 are 60, 40 and 50 JK-1mol-1, respectively. For the reaction,, ᐃH = - 30 kJ, to be at equilibrium, the temperature will be

Options

A.1250 K
B.500 K
C.750 K
D.1000 K

Solution


ᐃSreaction = 50 - = - 40 j mol-1
ᐃG = ᐃH - TH - TᐃS
at equilibrium ᐃG = 0
ᐃH = TᐃS
30 × 103 = T × 40
⇒     T = 750 K
